Hi
I changed mine a week and a bit ago for the Tein S-Tech's they feel fantastic, the ride is not much harder (if at all now they've settled down) than the stock springs, and certainly not harsh, the ride still feels fairly stock it doesn't crash over bumps BUT it's lost a good deal of the roll when transfering weight in corners, feels like it corners flatter if that makes any sense, so far very, very pleased with them.
Not sure where you are, but you're welcome to have a passenger ride in mine if your anywhere near Southampton.
If you are after a set I picked mine up from Camskill for £140 inc postage
